Description:
Abstract: This portion of the data release contains latitude, longitude, and water depth values for push cores and gravity cores collected from the Escanaba Trough vent field, Gorda Ridge, in the northeast Pacific Ocean. These data were collected in 2022 (USGS Field Activity 2022-621-FA).
Purpose: Data were obtained to characterize downcore geochemical properties of sediments. These data are intended for science researchers, students, policy makers, and the general public.
Supplemental_Information:

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report: No formal attribute accuracy tests were conducted.
Logical_Consistency_Report: No formal logical consistency tests were conducted.
Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report: The locations of push core samples were determined using ROV Jason’s ultra-short baseline (USBL) navigation. Accuracy for this depth is approximately 6-26 m. The locations of gravity core samples were determined using the R/V Thomas G. Thompson’s GPS navigation, which is accurate to less than 5 m. A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report: For push core samples, the vertical accuracy was determined with ROV Jason’s altimeter, which is accurate to less than 1 m. For gravity core samples, the vertical accuracy was determined with the R/V Thomas G. Thompson’s multibeam bathymetry system. No formal positional accuracy tests were conducted.
Lineage:
Process_Step:
Process_Description: Push core and gravity core samples were collected on the R/V Thomas G. Thompson between May 24, 2022, and June 13, 2022, during the TN403 Escanaba Trough expedition, which was led and staffed by USGS employees. Push cores were pushed into sediment at 37 locations by ROV Jason’s manipulator arm in water depths between 3201 and 3301 meters. Gravity cores were collected using a gravity corer at 7 locations in water depths between 3209 and 3304 meters. Gravity cores greater than 60 cm in length were cut into sections onboard the ship and labeled ‘X’ (0-60 cm), ‘Y’ (60-120 cm), and ‘Z’ (>120 cm). All cores were stored upright and refrigerated until return to shore.
